Are Criminals Born or Made? | The Nature vs Nurture Debate

Are criminals born that way, or does life create them?

In this episode of Killing Time with Friends, Billy, Melanie, and Hope explore one of the biggest questions in psychology and criminology: Nature vs. Nurture.

We dive into brain science, trauma, genetics, and real criminal cases to explore how violent behavior develops. From the shocking story of Phineas Gage to the controversial twin separation studies, we look at the science behind personality, impulse control, and behavior.

We also examine well-known criminals like Aaron Hernandez, Ted Bundy, Jeffrey Dahmer, and Richard Ramirez to ask whether their crimes were influenced more by biology, upbringing, or a complex mix of both.

By the end of the episode, we ask a difficult question:
Are killers created… or discovered?

This episode explores the psychology behind crime while emphasizing the importance of mental health awareness and early intervention.

Listen, think, and decide for yourself.
